Calling all pre-revenue founders: What is your step-by-step plan to make your first dollar?

I'm writing a book about how to get from 0-1 as an Indie Hacker.

If you are a pre-revenue founder I have a couple of questions for ya. It would be super helpful to hear your perspective on these questions:

• What your existing step-by-step plan to make your first dollar?
• What have you tried in the past?
• What didn't work out for you? Why?
• What are your worries and/or uncertainties?

Thanks in advance!
